I have an MDX mobile that is not working properly. When I push the on button, the radio begins to turn on and then all the lights and display go off. I checked some of the voltages on the DC input and they seem to be ok. Has anyone had this problem and know what it might be ???

I'm having this problem too. Power on the radio, the whole thing lights up on the self-check, and then it goes blank. Can't get it into program mode, so I can't check the feature data. Took the head apart and cleaned stuff, still same issue.
